Temperatures reached about -4 degrees Fahrenheit in Toronto on the night of January 3, CBC reported. Considering temperatures across the U.S. will match and even beat Canada early this week, residents might hear some cracks in the night, as well.

Although frost quakes don't share their causes with earth quakes, a seismograph — an instrument that monitors movement of the earth — can pick up the events, if the ground cracks close enough to the device. People experiencing frost quakes also often mistake them for earthquakes, perhaps the origin of the name.
